Quantitative chronological medical infusion device

Abstract

The present invention is a medical infusion and aspiration system delivering precisely timed and accurately calculated, adjusted pulsated delivery in high rates of flow delivering an effective profile of pulses tailored to provide momentary spikes of levels of freely available medicines based upon the uptake of the medicine and optimally on real time measurements of the medicine or response of the patient, termed Quantitative Chronological Delivery. The system comprises any pumping mechanism, and optimally a pumping mechanism, and a cassette or cartridge having a reservoir area where the plunger rotates as it advances in reference to the cartridge to provide additional accuracy and overcome the forces of inertia and slip-stick as well as eliminate backlash. Optimally, the systems incorporates an encoded area and an opening for connection to an infusion tube with an in-line sensor area where sampling probes are located. The infusion is adjusted in both amount and duration between pulses to provide quantitatively controlled, chronologically optimized infusion. A motor causes bi-directional pumping to allow for samples to be presented to the sensor area. The system accuracy allows for more concentrated medicines, as a sealed container can eliminate the need for diluting or withdrawing medicine to load a reservoir, and achieves extraordinary accuracy without error correcting software or expensive volumetric measurement and control systems.
